Laser-Welded Corrugated-Core Sandwich Composition—Numerical Modelling Strategy for Structural Analysis
Round 1
Reviewer 1 Report
In this paper, the authors introduced an efficient combined modelling method to product the structural response of corrugated-core steel sandwich panel (CCSSP) lightweight structures. The authors predicted CCSSP panel-level sectional forces using an EOSL-based global model, which is found to have good accuracy based on the comparation to a detailed 3D reference model, and analyzed the reason why the EOSL global model produces errors in the prediction of the membrane force in the weak direction. Besides, the authors discovered that the sub-modeling approach using shell composition configurations combined with a detailed 3D solid sub-model exhibited high accuracy. This research is comprehensive and detailed, and has important implications for achieving an accurate and reliable design and maximizing the use of CCSSP lightweight construction. Here are some things that could be improved.
Point 1. The full-text structure can be added in the introduction, so that readers can quickly understand the article.
Point 2. In the introduction, the author introduced the application prospects and difficulties of structural analysis of steel sandwich panels with corrugated core. Some relevant literatures can be added on this basis, so that readers can easily understand the research status of this structure.
Minor editing of English language required.

Dear Anonymous Reviewer # 3
Thank you for reviewing our manuscript and making valuable comments. The authors would like to briefly report what they changed in the manuscript on the basis of your comments:
Reviewer: The abstract is too long, please write the main contents.
Authors: The abstract was rephrased briefly to encapsulate the main contents according to the reviewer's comment.
Reviewer: Why using EOSL model? Show the merit of reason.
Authors: As part of the introduced combined sub-modeling technique, EOSL is used to efficiently obtain the displacements rapidly with relatively minimal computational effort, as highlighted in the manuscript. However, as the approach is incapable of capturing the stresses in the panel elements, the EOSL displacement outcome will be imported into the proposed sub-models, resulting in accurate stress predictions in the panel constituent plates. The description has been provided in the manuscript.
Reviewer: In Fig. 25, please show the detail of spring supports.
Authors: It was done based on the reviewer's comment.
